KROHNE SU 600 EN - Manual (Page 20)

The measured value indication shows the digital
indication value and also an analogue bargraph. Here, it
is absolutely necessary that the function switch is set to
position [ 0] ("OPERATE").
The following functions can be selected via the rotary
switch:
l
0: Measured value display and simulation
l
1: Relay 1 switching point ON
l
2: Relay 1 switching point OFF
l
3: Relay 2 switching point ON
l
4: Relay 2 switching point OFF
l
5: Decimal point position of the scaling
l
6: Scaling for 100 %
l
7: Scaling for 0 %
l
8: Changeover current output 0/4 ... 20 mA
l
9: Damping of the measured value (integration time)
l
A: Offset correction
l
B: Min. adjustment in % by modifying the level
l
C: Max. adjustment in % by modifying the level
l
D: Min. adjustment in mA without modifying the level
l
E: Max. adjustment in mA without modifying the level
l
F: Changeover current input active/passive
l
In active mode, SU 600 provides the power supply
for the connected sensor. Power supply and mea-
sured value transmission are carried on the same
two-wire cable. This mode is provided for connection
of transmitters without separate power supply (sen-
sors in two-wire version).
l
In passive mode, no sensors are powered, only the
measured value is transmitted. This mode is for
connection of transmitters with own, separate power
supply (sensor in four-wire version).
à
Set the function switch to position [F] and select the
suitable mode with the [+/-] keys. Save your settings
by pushing both keys simultaneously.
When a pressure transmitter is used, an offset correc-
tion should be carried out first. These instruments are
factory-set in a certain position. If the pressure trans-
mitter is now mounted in a different position, its
